Alpine Loop in the San Juan Mountains of Colorado. The road wasn't as narrow or the elevation as high but the scenic values were similar.
The infamous switchback and an editorial comment about how drivers negotiate this corner: While we were camped at the lake six vehicles drove through the switchback and down to the lake. Every single driver chose to make a two or three point right hand turn on the corner. Turning sharply to the right and driving to the edge of the road and then backing up. Repeating the process until their vehicle was headed down the road. A dangerous maneuver that risks catastrophe if an error is made.
The old timers did not make the turn in this fashion. In fact the vehicles that they drove couldn't have negotiated the corner the way modern drivers do. They constructed the road to avoid all the drama and used the "pull in, back up” method" to negotiate a tight pair of turns.
We could have driven the corner just like the old timers but a truck was parked on the upper landing blocking our path. So we had to make the three point turn. We would have pulled forward into the upper landing, backed about 60 yards down to the lower landing and then continued driving down to the lake.
My answer was that I didn't understand how to drive using landings until 1974 when my 70 year old grandfather explained to me how he drove roads in the Rockies back in the 1920's. He and his partner drove a two-wheel drive Model T Ford into some really remote locations. Sometimes I feel like a real light weight driving the back roads with four wheel drive, steel belted tires and a rear locker.
camped on the western flank of Glass Mountain and after sunset observed the lights of vehicles driving down this road.
